The impact of PPG on clinical outcomes\u2014including ascites response, overt hepatic encephalopathy (OHE), further decompensation, and mortality\u2014was evaluated using Fine and Gray competing risk regression models, both unadjusted and adjusted for potential confounders.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Results:<\/jats:title>\n            <jats:p>\n              A total of 143 patients were included in the analysis, of whom 65.7% had refractory ascites, with a median Child-Pugh score of 9.
